News Summary: Nasdaq blames human error for glitch

TO ERR IS HUMAN: The Nasdaq OMX Group blamed "human error" for a series of delays in the initial public offering of WhiteHorse Finance on Wednesday.

HELLO, WHITEHORSE: Nasdaq welcomed WhiteHorse Finance to the "family" on its Twitter feed more than an hour before the regular trading day. The company's stock made its entrance with an hour left before the closing bell, and WhiteHorse promptly sank from its $15 IPO price.

ONCE AGAIN: Nasdaq bungled the IPO of Facebook in May, when trading was delayed and others reported problems with orders.
